Is there a safe way to control mosquitoes?
Q: Are there any environmentally safe mosquito controls?
A: “Safe” is a fraught word. I feel safe lighting my water heater pilot but I have a friend that refuses to go near her heater when the pilot light stops.
I do not like systems that mist insecticide automatically during the day. With no human oversight, the mister can work during rainstorms, on a windy day, while kids are playing nearby, etc. Insecticide applied by humans is marginally better but I have major reservations. No matter how much the company claims the insecticide is “natural“, it is still something that kills insects. The mist will kill mosquitoes, butterflies, honeybees, and any other insect in its way. On a breezy day, the spray can drift onto neighboring properties.
So what do I recommend? For small outdoor spaces, a reciprocating fan works perfectly. Mosquitoes are weak flyers and the fan pushes them away while cooling you. For a hike in the woods, there are several repellants that work well but that do not contain DEET. I like products that contain picaridin. The feel of picaridin spray on my skin is much less oily than DEET. For a picnic out of the reach of electricity, self-heating mosquito repellent devices work nicely if there is not a breeze. These do emit a tiny amount of insecticide but they are MUCH more effective than citronella candles, mosquito coils, or mosquito repellent plants.
